Crede came up up from the farm with reputation of being a gold glover caliber 3B. So far he has not consistently shown that ability. He has shown flashes from time to time, but he'll never be confused with Brooks Robinson. Yet, he is "overrated". On this board, there is a tendency to form an opinion, the stick with it through think and thin. That's why Valentin still has a rep as a poor shortstop, after having 36 errors in 2000. Yet he was superior defensively in 2003.
Crede's no slouch at third. In fact, I'd call him somewhat above average. But I'd also still call him overrated.
